There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Oxo ligand functionalization in the uranyl ion
The reduction of uranyl (UO22+) to U(IV) is relevant to both the speciation of uranium in the environment and the geological storage of spent nuclear fuel. Several recent studies on uranyl reduction suggest that this process occurs in a step-wise fashion, transiently generating the unstable pentavalent uranyl ion (UO2+). Our laboratory is exploring the synthesis and reactivity of pentavalent uranyl, in particular the reactivity of its two oxo ligands, in an attempt to model the microbial reduction of UO22+. We are also exploring the stability of the U(VI) and U(V) oxidation states, as a function of ligand environment, and we have synthesized a series of uranium alkoxide, amide and alkyl complexes to support these efforts.
